Data Types – Category

The data type of a variable specifies which data it may contain. Certain operators and scripting commands require variables to be of certain types.

Definition

The data type of a variable depends on the value given to it on initialization.

myVar = ""; // myVar is now a String

a local variable should be prefixed with private (Arma 3) or local (Arma 2) to avoid a potential upper-scope variable overwrite:

private _myLocalVariable = "";	// Arma 3
local _myLocalVariable = "";	// Arma 2

Redefinition

The data type of a variable may be changed at any point of the game by just redefining the variable with another type.

myVar = "";	// myVar is a String
myVar = 0;	// myVar is now a Number

Magic Types

There are some magic data types, which are not really datatypes, as they do not describe any particular value.

Syntactical Helper Types

Some more types are used to provide for a construction of syntactically richer constructs than normal unary / binary operators.
